 iit the cost.al luargiii between the cell and the first discal line, and anotlier smaUer 



one 1)6} ond the second discal line. Hindwing : a discal line touching apex of 



cell, narrow, sometimes indistinct in front, another near it, abbreviated or obsolete, 

 a third convex in front, tlien concave, narrow, and a black line ontside the third 

 at aual angle reaching np to M- ; veins with minute black streaks at extremities. 



riidcrftidr. Forewing : markings similar to upperside, loss distinct, those 



in basal half red, the snbbasal line vestigial, straight streak in apex of cell as on 

 upperside in the direction of IT', snbapical white spot larger and more strongly 

 ]irojecting distad before SC', tlie otlier (wo wliite jjatches restricted to the costal 



margin. Hindwing : lines nearly as above, but blackish brown, interspace 



l)etween second and third, or nearly the whole wing, shaded with wliitc, a sliort 

 white line before apex, marginal area very faintly shaded with white. 



c?. Tenth tergite broad, sides undulate (PI. XXIV. f. 9: apex broken in tiic 

 only specimen at disposal : it is apparently cleft or sinuate) ; sternite ]iroduci'd into 

 a long, slender, cylindrical, slightly club-shaped process. C'lasper (PI. XXXIIl. f. 1 j 

 narrowed towards apex, ventral margin dilated near base, then emarginate : harpe 

 represented by a proximal, pointed, slightly curved process which stands far apart 

 from the clasp(!r, the processes of the two sides being close together and visible 

 lietween the claspers without dissection. Peuis-sheath (PI. XXX. f 23) stout, jug- 

 shajiod, the apical margin produced laterad : penis-funnel (I'-t) with a short, ventral, 

 carinate process. 



?. Vaginal plate (Pi. XVII. i'. :>) resembling to a certain extent that of 

 /'.sc/frhchiiiiii jinMiai ; antevaginal jmrt i/ii'p) mesially folded, a large groove at 

 each side; vaginal orifice (F) situated between two compressed jjrocesses, which 

 are curved mesiad and are pointed, lesembling somewhat a bird's liead and l)reast ; 

 post-vaginnl part (/"'/'; slightly sunken proxiiiially, the greater part membranaceous, 

 scaled. '"
